FILM-REEL.

Specification of Letters Patent. Patented Nv, 30, 1920.

Application led April 8, 1918. Serial No. 227,412.

v Ta all 'whom it ma concern:

The object of my invention is to provide a film reel to which the end of a film can be attached very quickly and in the proper direction.`

' Another object islto provide a constructionwhich 'is easily accessible for the threading of a film.

Another'object is to provide a hub insert with a plurality of key-slots to increase the opportunity of catching the key on the reel shaft when the reel 'is being mounted.`

Another object is to provide a construction that will make the reel rigid and still fit the machines and apparatus now in use.

Vvse

Another object is to provide an easily demountable structure so that each part of the reel canbe renewed when worn.

Referring to my drawings:

Figure 1 is a side elevation, partly in cross-section.

Fig. 2 is a cross-section through the reel.

Fig. 3 is an outside view.

Fig.4 is a'partial side view.

As shown inFig. 1 v'the side plates 1 and 2 are fastened to the Vhub members 3 and 4, lylflthe male and female screw-bolts 5 and 6.

e hub vmembers 3 .andn are fastened to- .gether' by the, maley and lfemale screw-bolts on to the steel insert. 9. This insert is pro-V vided with six key-slots on each 4end to receive the usual key`10 on the reel supporting shaft 11.

On the hubmembers'i3v and 4c are mounted three springs 12, `13 .and 14, and one member springs point in one direction thereon and in the opposite` direction. on vthe other member (see Fig. 3L). so that the-film can'be engaged therebyinoney direction'onl from the side nearest'to the operator, and 't ese springs are vprovided with-little projections 'XX`, by

means which `projections these .s said in the art without the periphery thereof, saidy springs bein M inay be of heavy material without materially mcreaslng the weight of the reel, and the edges of the plates can be a perfect radius to prevent injur to the film.

The hub-mem ers 3 and 4, when mounted together are of standard width so as to be attachable to existing standard reel shafts, the side plates 1 and 2 being extended over the standard width at a point where they cannot interfere with the standard dimensions of a film apparatus.

While I have shown and described a specific structure embodying the principles of my invention, I wish it to be understood that my invention in its broad scope as defined by the claims is not to be limited or restricted thereto, as many changes'in details of construction will readil appear to those skilled eparting from the contemplated spirit and scope of my invention:

What I claim as my invention is:

1. In a film reel, a hub of standard width, side plates fastened thereto, and said side plates extending beyond the width of the hub, said side plates having spokes and each of said spokes having a notch, a sprlng fastened to the hubs and extending through the notches, one set of said springs pointing in one direction and the other set in the opposite direction, said notches limiting the movement of the springs.V

L'. In a film reel, a hub, side plates secured thereto, said side' plates havmg radiating spokes, said hub having aset of vsprings on the vperiphery thereof adgacent each spoke, the springsof each set belng secured to the hub at their respectively opposite ends whereby the free ends of said springs point other.

3.l In aV-ilm reel, a hub having'springs'on ranged in sets and the members/of eac 'set being secured to the hub at respectively opposite ends and having their free ends disposed in opposite directions with respect to each other.

4. In a film reel, 'a hub composed of sections, an insert arranged intermediate said sections and to which said sections are secured, side plates secured to' said hub and spring clamping devicesl mounted onV the periphery of said lhub 'between the side 10 plates. 't .i
